RELATED APPLICATIONS

The present application is a Continuation-In-Part of U.S. patent application Ser. No. 10/679,648, entitled Wheel Ornamentation Assembly, filed Oct. 6, 2003, to which priority is claimed under 35 U.S.C. §120, and of which the complete disclosure is hereby expressly incorporated by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to wheels for vehicles and, more specifically, to a wheel ornamentation assembly for wheels of a vehicle.

2. Description of the Related Art

It is known to provide wheel ornamentation such as wheel caps and wheel covers for wheels of a vehicle such as an automotive vehicle to enhance appearance of the wheels. Wheel ornamentation is used because it is less expensive to manufacture, finish, and mount the wheel ornamentation to the wheel than to manufacture the wheel with the same quality finish of the wheel ornamentation. A chrome surface on the wheel ornamentation is an inexpensive alternative to chrome plated or polished wheels. In addition, wheel ornamentation provides various types of appearances and styling variations, all of which may be combined with a single wheel design.

It is also known to manufacture the wheel ornamentation of a plastic material and attach the plastic wheel ornamentation to lug nuts of the wheel. An example of such a wheel ornamentation is disclosed in U.S. Pat. No. 6,022,081 to Hauler et al. In this patent, an ornamental wheel cover is provided with a number of elongated tubular extensions axially projecting from the cover that are each partially slotted to provide cantilevered fingers. Each finger has an undercut groove that has a shoulder, which positively positions the cover to an upper shoulder of the lug nuts of the wheel. Below the undercut groove is a bulbous portion that contacts the lug nut below the flange and engages the underside of the flange, thereby retaining the cover on the lug nut.

While it may be preferable for a wheel ornamentation to operatively engage the lug nuts of a wheel, concern arises over reliable engagement of the lug nuts by the wheel ornamentation because of the different thermal properties between the wheel ornamentation and the lug nuts. Specifically, lug nuts are heated by the wheel as the wheel rotates, thereby heating the extensions of the plastic wheel ornamentation. As a result, the heated plastic may relax, causing the retention force of the extensions to decrease. The decreased retention force of the extensions may result in the wheel ornamentation disengaging the wheel.

To counter the effects of heat on the retention areas of a plastic wheel ornamentation, it is known to employ a wire retainer to provide mechanical support. However, there remain applications where employing a wire retainer is less desirable, as it increases cost as well as the steps of assembly relating to the wheel ornamentation. As a result, a plastic wheel ornamentation that effectively disperses heat radiated by the lug nuts and/or includes increased structural support for the retention areas to absorb the radiated heat without compromising the retentive ability of the wheel ornamentation is preferred.

Accordingly, there is a need in the art for a plastic wheel ornamentation for operatively engaging the lug nuts of a wheel having increased structural support at the retaining areas. Further, there is a need in the art for a plastic wheel ornamentation with improved heat dispersion retaining areas to provide reliable retention to the lug nuts throughout the acceptable product life of the wheel ornamentation.

SUMMARY OF THE INVENTION

Accordingly, the present invention is a wheel ornamentation assembly for attachment to a wheel secured to a wheel hub with a plurality of lug nuts. The wheel ornamentation assembly includes a wheel ornamentation body having an outboard surface and an inboard surface. The wheel ornamentation includes clusters of retention legs that extend axially from the inboard surface and are arranged in circular patterns to receive the lug nuts therein. Each of the clusters of retention legs includes a gap which extends to the inboard surface. Each of the clusters of retention legs further includes a plurality of primary retention legs arranged in opposed pairs on either side of the gap and a pair of secondary retention legs arranged in opposed positions on either side of the gap. Standoff structures for abutting a front edge of the lug nuts are provided on only the primary retention legs.

One advantage of the present invention is that a wheel ornamentation assembly is provided for a wheel of a vehicle. Another advantage of the present invention is that the wheel ornamentation assembly has support walls that provide structural support for plastic wheel ornamentation, without which the plastic wheel ornamentation may relax under stress and/or heat. Yet another advantage of the present invention is that the wheel ornamentation assembly includes a channel that directs heat away from the retaining area. Still another advantage of the present invention is that the wheel ornamentation assembly includes integrated retaining areas to reduce steps in the manufacturing process required for multi-component wheel ornamentation assemblies as well as to reduce the steps in the assembly and installation process. A further advantage of the present invention is that the wheel ornamentation assembly has stand-off features, which contact the top of the lug nuts, providing a positive-stop during installation. Yet a further advantage of the present invention is that the wheel ornamentation assembly has a shoulder in spaced relation to the top of a lug nut flange to provide an over-install limiter during installation. Still a further advantage of the present invention is that the wheel ornamentation assembly has plastic legs that grip on the outside of the lug nut.

Other features and advantages of the present invention will be readily appreciated, as the same becomes better understood, after reading the subsequent description taken in conjunction with the accompanying drawings.
